I've been to Distrito many times. It's great! They have great guacamole and even better margaritas. The plantains are to die for, as well as their ceviche.
Garces is by far my favorite chef so I'm a bit partial to his restaurants. It's a really nice place, but not his best. It's a bit over priced for south american food that you can get at other places, in my opinion.
Don't get me wrong, it's really great food, but I suggest some of his other restaurants for a really nice night out.
